SHOE-LINING TRllVllVlER.

SPECIFICATION forming part of Letters Patent No. 707,906), dated August26, 1902.

Application led March 6,1902.

To @ZZ whom it may concern:

Be it known that I, CHARLTON BAYSE COR- WIN, a citizen of the UnitedStates, residing at Jefferson City, in the county of Cole and State ofMissouri, have invented certain new and useful Improvements in ShoeLining Trimmers, of which the following is a full, clear, and exactdescription.

My invention is a shoe-lining trimmer, and is intended to do certainwork relating to the trimming of linings of shoes, said work having beenheretofore done by hand.

Reference is to be had to the accompanying drawings, forming a part ofthis specication, in which similar characters of reference indicatecorresponding parts in all the gures.

Figure 1 is a side elevation of a machine embodying my invention. Fig. 2is a perspective View of the cutting-block. Fig. 3is a plan view of thegage. Fig. 4 is a section of the same upon the linewoc in Fig. 3. Fig. 5is a plan view of the unfinished shoe from which the linings are to betrimmed.

Upon a frame 1 is mounted a pair of bevelgears 2 3, the same beingactuated by means of the belt 4, leading from any suitable source ofpower. A table 5 is mounted upon the frame and is adjustably securedthereto by means of the brackets 6 7, which are provided with slots 8 9,said slots being engaged by the adjusting-screws 10 11. A tongue 12 iscut in the table and is depressed, as shown in Fig. 1. A revolubledisk-shaped cutter 13 is mounted upon the shaft 14 and secured theretoby a knife-screw 15. The table 5 is separated from the revoluble cutter13 bya small space 17. A cutting-block 18 is-loosely fitted upon thetable 5 and is adjustable relatively thereto by means of a screw 19 andis also adjustable relatively to the revoluble disk 13. At 18n thecutting-block 18 is provided with an angular edge which closelyapproaches the edge of the cutter 13 and which is adjustable relativelythereto by adjusting the cuttingblock. If desired, the cutting-block canbe adjusted'that its cutting edge has loose contact with the revolublecutter, so that the edge of said cutter passes against the edge 18 ofsaid cutter-block with a motion analogous to that of a pair ofscissors-blades. The cutting-block 18 is mutilated by undercutting thesame in 'rear of the angular edge 18 there- Serial No. 96,908. (Nomodel.)

of, as will be seen by reference to Figs. 1 and 2, and this undercutportion of the block leaves a space between the free overhanging end ofsaid block and the table, into which space is adapted to enter thecuttings which are severed from the shoe-lining by the operation of therotary cutter. A gage 23, having a substantially spocn-shaped end 23, asshown more particularly in Figs. 1 and 3, is loosely litted upon thecutter-'block 18 and is adjustable thereon by means oftheadjusting-screws 2122. The shoe-lining is shown at 24E, and the facingis shown at 25 in Figs. 1 and 5.

The operation of my device is as follows: The parts being arranged asindicated in Fig. 1,the unfinished shoe is laid upon the table,thefacing being loosely placed over the gage 23. The shoe is then fed in adirection laterally with reference to the position of the revolublecutter and the cutter severs the superfluous cloth from the shoe-lining,as indicated in Fig. 1. The facing 25 merely glides over the rotundsurface of the gage 23. It will be noted that the table 5 is adjustablerelatively to the frame and the general position of the knife, that thecutter-block 18 is longitudinally adjustable relatively to the table andto the edge of the revoluble cutter, and that the gage 23 islongitudinally adjustable relatively to the cutter-block 18, to thetable 5, and to the revoluble cutter 13. By means of these adjustmentsalmost any desired position can be given to the several parts and therevoluble cutter may be used in a multitude of relations. The work` ispreferably fed in the sa me direction that the cutter travels, so thatthe cutter acts to some extent as a feed.

I find that by the above arrangement eX- cellent cutting can be donewith a comparatively dull cutter, provided the same be given a suitablespeed. The revoluble cutter is easily detached for the purpose ofgrinding and is easily replaced by another revoluble cutter.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A shoe -lining trimmer, comprising a frame, atable, a revoluble cutter mounted on the frame, a cutting-block mountedon the table and having an undercut overhanging IOO itself and thetable, and said gage extending beyond said overhanging end of thecuttingblock.

3. A shoe -lining trimmer, comprising` a frame, a table, a revolublecutter mounted on said frame, means for adjusting said table relativelyto said cutter, a cutting block mounted on said table and provided withan overhanging end forming a space between itself and the table, saidend of the cuttingblock terminating in an angular edge which is inopposing relation to the face of the cutter, and means whereby saidblock may be adjusted relatively to said revoluble cutter to vary thedistance between the angular edge of the block and the face of thecutter.

4. A shoe -lining trimmer, comprising a frame, a revoluble cuttermounted thereon, a table, a cutting-block adj ustably secured to saidtable, said cutting-block being provided with an overhanging end forminga space between itself and the table, and said end terminating in anangular edge, means whereby said cutting-block may be adj ustedrelatively to the face of said cutter, and a gage projecting over theoverhanging end of the cuttingblock and beyond the angular edge thereof.

5. A shoe -lining trimmer, comprising a table, a revoluble cuttermounted adjacent thereto, a cutting-block to be secured upon said table,said cutting-block being provided with an angular edge, and a gageprovided with a substantially spoon-shaped end to be secured upon saidcutting-block, the arrangement being such that said gage overhangs saidcutter and is adjustable relatively thereto.

v6. A shoe -lining trimmer, comprising a table, a revoluble cuttermounted adjacent thereto, a cutting-block to be secured upon saidtable,said cutting-block being provided with an angular edge, a gage mountedupon said cutting-block and provided with a downwardly-projecting endoverhanging the edge of said cutter, and means for adjusting the heightof the table relatively to the operating edge of said cutter.

7. A shoe -lining trimmer, comprising `a table, a-revoluble cuttermounted adjacent thereto, a cutting-block provided with an anguiarsurface and also provided with a mutilation adjacent to said surface,and means for adjustably securing said cutting-block upon said table,the arrangement being such that said cutting-block may be so adjusted asto present said angular edge immediately adjacent to said revolublecutter by leaving a vacant space between said angular surface and saidtable.

In testimony whereof I have signed my name to this speciiication in thepresence of two subscribing witnesses.
